LR41 Battery Equivalent
LR41 is the same cell as 192, AG3 and LR736, so any of those codes will fit; SR41 is the same size in silver oxide and holds a steadier voltage for longer.

Upgrade or downgrade
Same size, different chemistry. Read the verdict before you buy.
| Cell | Chemistry | Voltage | Verdict |
|---|---|---|---|
| SR41 | silver oxide | 1.55 V | Upgrade Upgrade: steadier voltage, longer life. |
Similar size, check the fit
Same diameter, different thickness. These are not drop-in replacements.
| Cell | Size | Verdict |
|---|---|---|
| LR48 | 7.9 × 5.4 mm | Same 7.9 mm diameter, but 5.4 mm tall instead of 3.6 mm. Only if the holder fits; thinner cells can lose contact. |
| LR721 | 7.9 × 2.1 mm | Same 7.9 mm diameter, but 2.1 mm tall instead of 3.6 mm. Only if the holder fits; thinner cells can lose contact. |
| LR726 | 7.9 × 2.6 mm | Same 7.9 mm diameter, but 2.6 mm tall instead of 3.6 mm. Only if the holder fits; thinner cells can lose contact. |
| LR731 | 7.9 × 3.1 mm | Same 7.9 mm diameter, but 3.1 mm tall instead of 3.6 mm. Only if the holder fits; thinner cells can lose contact. |
Do not use
These are the same size or a similar code, and they are not equivalents.

312
Zinc-air hearing-aid cell: same size, but 1.45 V, needs air holes and drains once unsealed.
About the LR41 cell
Alkaline version of the same size; voltage sags as it drains.
LR41 questions
